That fire had to be either fuel fed or bearing oil fed. Can't think of anything else in there to burn like that. Kudos to the crew to getting back on the ground ASAP. With that much flame coming out the top of the nacelle, those engine mount attachment points were not going to hold out for very long. (Although, assuming the engine neatly fell off without damaging anything else on the plane, and also assuming the plane could handle the resulting weight imbalance, maybe letting go of a dead and burning engine might not be the worst thing....)
